Figure 3: Salivary alpha-amylase concentrations during waking hours following sleep at home or sleep in the lab. Daily profiles were assessed by having subjects provide multiple samples throughout the day, beginning immediately upon awakening and finishing prior to going to sleep. Samples were provided following sleep at home (Baseline), the 1st and 2nd nights in the sleep laboratory (Lab 1 and Lab2) and again once subjects resumed sleeping at home (PostLab). Salivary concentrations levels varied throughout the day (P<0.00001) but were not influenced by where the subjects slept the preceding night.
